Producer Surplus-

Consumer surplus is 30.00: the buyer side is capturing real value.

  • You are willing to pay 100.00 but the price is only 70.00, so you keep 30.00 in surplus - real economic value in your pocket.
  • Consumer surplus represents the gain from trade: the difference between your reservation price and what you actually hand over.
  • Individual surplus varies by buyer: someone who values the good more will capture a larger surplus at the same price.

Next stepSwitch to Market mode to model how surplus is distributed across all buyers and sellers using linear supply and demand curves.
